Abstract (en)
[origin: EP2551997A2] A geared cooling device (10) and method of manufacturing a geared cooling device (10). The cooling device (10) includes a fan shaft (48), a fan coupled to the fan shaft (48) and a speed adjuster 108 coupled to a motor shaft (18) of a motor (12) and coupled to the fan shaft (48). The speed adjuster 108 adjusts a rotational speed of the fan shaft (48) to cause the fan shaft (48) to rotate at a different rotational speed than the motor shaft (18) to facilitate passing cooling air past the motor (12). The method of manufacturing includes coupling the speed adjuster 108 to the motor shaft and to the fan shaft (48).
